where to get RO/DI water?

[gobytron]

technically, this unit IS and RO/DI unit and I would be very surprised if it didn't give you a better tds reading than water from the store...

I think what Vic means is that since the OP is in Calgary that has far higher TDS than Vancouver, the DI beads in the AP Tap Water Filter would exhaust far more quickly than on extremely soft Vancouver water. As a result, using that filter in Calgary would be less economical.

chances are you'd still come out ahead over buying the H20 retail...

Yup........ I've heard some people get around 300 gallons using the tap water filter in our 15ppm water

I think Calgary averages 160ppm.

How often do you have to change the filter of these Aquarium Pharmaceuticals Tap Water Filter?

[fkshiu]

It depends on how much you use them and the quality of your water. On super-soft Vancouver water, I usually got at least a couple hundred gallons before the beads changed colour.

Township of Langley does yearly testing they post on their website, newest shown is 2009, but it gives a decent overview of the crap in your water.

Has any one tried with water in Canadian Tire? they seem like RO water contains 0 minerals, for $4.99 you can 5 gallon. I only have a 34 gallon RSM so I think I'll change 5 gallon every 2 weeks, is that gonna be ok?
or does any one recommand water from super store or walmart?
